CASTER.

SPECIFICATION forming part of Letters Patent No. 439,546, dated October 28, 1890.

Application filed August 4, 1890. Serial No. 360,855. (No model.)

T0 all whom t may concern:

Be it known thatI, JOHN I. NEssLE, a ctizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvement in Casters, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which my invention appertains to make and use the same, reference being had to the accompanying drawings, in which- Figure l is a perspective view of.A my improved caster combined with a circular socket. Fig. 2 is a perspective view of my improved caster combined with a iiat socket. Fig. S is a detailed end view of the spring-holder.

The object of the invention is to provide a caster-truck which will form a guard as well as a support for a sprin g to be secured thereto, the purpose of which is to secure the truck and wheel to the socket of the caster in the simplest and most effectual manner.

My invention consists of the novel construction and arrangement of parts, as will be hereinafterdescribed, and particularly pointed out in the claim at the end of the specification.

ln the accompanying drawings, A designates the main truck of the caster, the lower back part of which is provided with a projecting spring-holder B, which is provided with two projecting flanges or guards C O and a perforation a. A spring D is formed with a lip In at one end, and it is perforated atc at the other end to receive a screw or rivet (l, which extends through the hole in the spring holder B, and the hole in the spring D.

The flanges C O on the outer portion of the spring-holder B extend beyond the face of the sprin g D and protect it against accidental fracture and dislocation by forming a guard for it.

The socket E is in each instance provided with a projecting rib or ange F, over which the lip of the spring extends, holding the caster-truck against movement awayfrom the socket. The resiliency of the springholds it normally into contact with the track G on the flange F.

The circular socket shown in Fig. l is screw-threaded and provided with a polygonal nut-shape lower portion H to receive a wrench, or a hole l to receive a pin or tool with which to screw and unscrew it to fix it into place on a piece of furniture or to remove it, as may be desired. The socket shown in the other figure is an ordinary one in general use.

The wheels F F are securedin place in the usual manner.

The spring D is made of any suitable niaterial-such as sheet-brass or steel-*and they may be die-stamped into the desired size and shape. The curved end will be inclined on its face at the point K, and the spring will yield enough to allow the spindle L to be readily slipped into place, where it will be held by the spring, as shown.

Having described the objects, uses, and advantages of my device, what I believe to be new, and desire to secure by Letters Patent, and therefore claim, is

In a caster, the truck having a projecting spring holder provided with projecting flanges or guards, in combination with a spring having a hook or lip and secured to said spring-holder between the guards, and a socket provided with a projecting ange engaging said hook on the spring, substantially as described.

In testimonywhereof I affix my signature in the presence of two witnesses.

JOHN P. NESSLE.
